MODE OF CONSTRUCTING BARB-WIRE FENCES, 800.

, SPECIFICATION forming part of Letters Patent No. 452,002, dated May 12,1891.

Application filed May 1,1890. Serial No. 350,252. (No model.)

My invention relates to an improvement in v the construction of barb-wire fences, of which the object is to prevent the damaging and crippling of live stock, especially horses. To obtain this I form a fence-wire supplied with revolving hub-barbs, as those represented in Figure 1. In Fig. 2 is the View of hub-barb cl, represented just after being cut out of sheetiron. Fig. 3 represents a flat barb supplied with a hub.

The fence-wire, as represented in Fig. 1, is formed out of two parallel running strands of wire, which are held togetherby an additional wir'e. Said additional wire forms at the same time the perpendicular or oblique standing axis for revolving hub-barbs.

Letter a designates the parallel running strands of wire; letter Z), the additional wire; letters 0 and (Z, hub-barbs. One or both of the two parallel running strands of fence-wire can alsobe used asahorizontal axis forbarbs; The barb (l,which is out out of sheet-iron,and represented in its first flat stage in Fig. 2, has to be formed in a tub, or rather hub, which will then have the points radiating from the center of the hub. The barb cis also cut out of sheet-iron and then provided with a hub. One of the ad vantages of these hub-barbsis the position the points of the barbs are placed in. Any pressure on the same will not bear directly on the center of the axis, but sideways, and on that account the revolving of the barbs is greatly facilitated.

By the use of this fence, with its hub-barbs, it is almost impossible for a horse to injure itself, either by running against the wire or by having its limbs sawing over the barbs at the opposite side of the fence. At the same time the fence will prove itself an effectual barrier against stock. By forming these tub-barbs with only two points a horse can be wrapped up in the wire and still the barb-points would not rip open skin and muscles, like other barbs. Of course with barbs which only have two points the points have to be in opposite directions and the barbpoints have to be moderately heavy at their base, so that by means of their gravity and the oblique position of the barb axis the two barb-points would be always at the lower side of the hub, and consequently the barb-points of said barbs will'stand at a right angle with the fence. out the hub (on perpendicular and horizontal axes) by having the same convex instead of entirely fiat. This barb also would be then, to a certain extent, a modified hub-barb.

Of course all mentioned barbs can be made with more or less points than shown in drawings.

What I claim as my invention, and desire to secure by Letters Patent, is

In a barbed fence, afence-Wire composed of two parallel strands intersected by a third passing diagonally back and forth between the parallel strands and twisted at the point of contact, in combination with. a barb rotating on said third strand, all substantially as described.
